The Simple Event Planner plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘&custom[add_seg][]’ parameter in versions up to, and including, 1.5.4 due to insufficient input sanitization and output escaping. This makes it possible for Contributor-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
